The Timeslip concept was a series of two-page showcases in the Marvel Visions book. In each one, a then-trendy artist would redesign a classic Marvel character. Some were simple physical redesigns while others took on a much more radical change in appearance and backstory. Not all of the Timeslip characters could have existed in the same alternate universe, as several have conflicting histories to each other. If something is not mentioned in the entry, then it is not included in the profile. Thus, any potential relatives, allies, etc., have been left unaccounted for, as these worlds could be alternate (some of which obviously are) or divergent (some of which seem to be).

Most, but not all, of the Timeslip profiles were reprinted in Timeslip: The Collection.
